Abstract

PURPOSE: To prevent condensation drops, which enter from an outer shell side, from entering an indoor side to smoothly discharge the drops outside. CONSTITUTION: A first drain groove 11a and a second drain groove 11b, which are substantially U-shaped, are formed integrally on rear and side surfaces of an indoor casing 8, 9, which is vertically divided into two upper and lower portions, to be connected to a drain groove 9b provided integrally on the lower casing portion 9. With such arrangement, condensation drops entering from an outer shell side can be smoothly discharged outside from the drain groove 9b without entering an indoor side through a joint 8a of the upper and lower casing portions 8, 9.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an integrated air conditioner, and more particularly to a drain groove provided in an indoor casing.

[0002]

2. Description of the Related Art In a conventional integrated air conditioner, a bottom plate 2 is divided into an indoor side and an outdoor side by a partition plate 4, for example, as shown in FIG.
As shown in, the indoor side heat exchanger 5, the sirocco fan 6 and the like are disposed in the upper and lower casings 8 and 9 that divide the indoor side into two parts, and the outdoor side heat exchanger 14, the propeller fan 13, and the outdoor side heat exchanger 14,
A compressor and a unit including a fan motor 12 for driving the sirocco fan 6 and the propeller fan 13 are housed in the outer case 3 so that the unit can be freely taken in and out, and the front surface of the outer case 3 is covered with a front cover. It was a structure to be worn. With the above configuration, the dew condensation water entering from the outer body 3 side is provided with a sealing material 10 such as a sponge in a gap between the outer body 3 and the upper part of the partition plate 4, and the upper casing 8 and the partition plate 4 are provided. It prevented the entry into the gap between them. However, when the water content of the sealing material 10 such as the sponge exceeds the allowable water content, the sealing material 10 overflows from the sealing material 10 and the upper casing 8 and the partition plate 4.
There is a problem that it enters the space between them and enters the room from the joint portion 8a of the upper and lower casings 8 and 9 which are divided into two. As a measure against the above-mentioned problem, a measure such as adhering a vinyl tape between the upper casing 8 and the upper part of the partition plate 4 and the sealing material 10 is taken, but when the unit is taken in and out of the outer case 3. The vinyl tape peeled off, and as a result, condensed water invaded the room.

SUMMARY OF THE INVENTION In view of the above problems, the present invention provides an integrated air conditioner capable of smoothly discharging dew condensation water entering from the outer case side to the room side without entering the room side. The purpose is to provide.

[0004]

In order to solve the above-mentioned problems, the bottom plate is divided into an indoor side and an outdoor side by a partition plate,
A vertically divided casing is provided on the indoor side, an indoor heat exchanger, a sirocco fan, etc. are provided in the same casing, and an outdoor heat exchanger, a compressor, and the sirocco fan and propeller are provided on the outdoor side. In the integrated air conditioner, a unit having a fan motor for driving a fan and the like is housed in and out of the outer case, and a front cover is attached to the front surface of the outer case. A drain groove for guiding condensed water to a drain drain groove provided on the bottom surface of one side surface of the lower casing is provided on one side surface and one side surface of the lower casing from the back surface of the above. Also, the drainage groove,
A first drainage groove which is integrally formed with the upper casing by opening and tilting upward on the rear surface of the upper casing, and a substantially vertical body which is continuous with the first drainage groove and opens at the front and is integrally formed with the upper and lower casings. It is characterized by comprising a second drain. Further, the joining portion of the upper and lower casings of the second drain groove is formed so that the upper casing side is formed in an inverted substantially L-shape and the lower casing side is formed in a substantially L-shape.

[0005]

With the above construction, the integrated air conditioner can smoothly drain water from the drain drain to the outside without water entering the outdoor side.

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1 and FIG. 2, 1 is a main body of an integrated air conditioner, 2 is a bottom plate on which a unit to be described later is mounted in the main body 1, 3 is an outer case for accommodating a bottom plate 2 on which the unit is mounted, and which can be freely taken 4 is a partition plate that divides the bottom plate 2 into an indoor side and an outdoor side, 5 is an indoor heat exchanger provided on the indoor side facing the air outlet, and 6 is behind the indoor heat exchanger 5. The sirocco fan 7 provided opposite to each other is a suction port formed between the sirocco fan 6 and the indoor heat exchanger 5,
8 is an upper casing of a casing that is vertically divided into two parts on the indoor side, 8a is a joint between the upper and lower casings, 8b is an inverted substantially L-shaped portion formed on the same casing 8 side of the same joint 8a of a drainage groove, which will be described later, Reference numeral 9 is a lower casing of a casing that is vertically divided into two parts on the indoor side, and 9a is formed on the lower casing 9 side of the same joint portion 8a of a second drainage groove, which will be described later, corresponding to the reverse substantially L-shaped portion 8b. An L-shaped portion, 9b is a drain drainage groove integrally provided on one side bottom of the lower casing 9 for guiding drain water to a drain port, and 10 is the upper casing 8, the upper portion of the partition plate 4, and the outer body 3. Sealing material made of sponge, etc., provided in the gap between, 11
a is a substantially U-shaped first drain groove that is integrally formed by inclining to the back side of the casing 8 and opening upward, and 11b is the upper and lower casings so that the drain groove 11a is connected to the drain drain groove 9b. A second drainage groove of a substantially U-shape integrally formed by opening the front side substantially perpendicularly to the side surfaces of 8 and 9, 12 is a fan motor for driving the sirocco fan 6 and the propeller fan 13, and 14 is a chamber. It is an outer heat exchanger. With the above configuration, as shown in FIG. 2, the first drain groove 11a receives the condensed water that has flowed into the gap between the upper casing 8 and the partition plate 4, and the second drain groove 11b to the drain drain groove 9b. 2B, the reverse substantially L-shaped portion 8b and the substantially L-shaped portion are shown in FIG.
By joining with 9a, it becomes possible to prevent dew condensation water from entering the room side from the joining portion 8a.

With the above construction, as shown in FIGS. 1 and 2, the sealing material 10 made of sponge or the like is formed in the gap between the outer shell 3 and the upper part of the partition plate 4 to prevent dew condensation water entering from the outer shell 3 side. Is provided to prevent entry into the gap between the upper casing 8 and the partition plate 4, and when the water content of the sealing material 10 exceeds an allowable content, the sealing material 10 overflows from the sealing material 10 and Condensed water that has entered the gap between the casing 8 and the partition plate 4 is received by the first drainage groove 11a, guided from the second drainage groove 11b to the drain drainage groove 9b, and enters the indoor side from the joint portion 8a. It becomes an integrated air conditioner that can be discharged to the outside without causing it.
